NovAtel Inertial Explorer v11.0: GNSS/INS Post-Processing Software

Inertial Explorer v11.0 is the latest release of NovAtel’s industry-leading post-processing software for GNSS and inertial navigation systems, announced in November 2025 . It processes data from GNSS receivers and IMUs to deliver high-precision position, velocity, and attitude solutions for applications such as mobile mapping, aerial surveying, and hydrographic surveying .

Key New Features in Version 11.0

Waypoint QC (Quality Control)

A powerful new tool that enables users to quickly assess post-processing quality and export project summaries to a compact PDF file containing processing settings, data quality metrics, post-processed plots, and statistics .

Processing Improvements

  • ARTK Enhancement: Auto-detection of base station receiver type with improved coarse alignment and heading updates

  • Fixed Integer Solution: Enhanced performance with increased alignment speed and robustness

Utilities & Data Access

  • Seamless UNAVCO Service Access: Streamlined connection to UNAVCO data services

  • BZIP Compression Support: Improved access to multi-constellation and high-rate base station data

Command Line Interface (CLI) Enhancements

  • Linux CLI Support: New WPGCMD and WPGCMDIMU commands for Linux environments

  • Attitude Rotation: Ability to rotate attitude values into a user-defined frame during export

  • Multi-Output Support: Up to 8 output files can now be specified during export

Core Capabilities

GNSS/INS Processing Modes

  • Loosely Coupled: Two-stage processing where GNSS trajectory is processed first, then passed to the INS processor

  • Tightly Coupled: Simultaneous processing of GNSS and INS data, maximizing GNSS availability in challenging conditions. Supports phase updates even with as few as two satellites available, significantly limiting inertial error growth
